Heh.
My college ride was a '46 Willys CJ2A, flat head four, 5.38 rear end, two speed transfer case, the whole headache.
Was a little faster than 45, but my jeep club was usually annoyed when I went along on mountain rides as they liked to run together on the highway to and from... and they had to slow to my maxed out, screaming speed of barely around 55.
:) It was great!
